Sede de la bolsa de mercados y valores de madrid Permíteme que te explique cómo decidí que la inversión en bolsa era el camino que quería seguir para rentabilizar mis modestas inversiones. Todo empezó por una (creo que sensata) preocupación por cómo llegaría al momento de mi jubilación . La primera preocupación, y aunque parece remota, era siquiera si iba a disponer de una jubilación y la segunda, si la cantidad a percibir cubriría lo q....

No te sientas solo, es lo más normal. Y lo digo porque a mi me pasa exactamente lo mismo: es un mundo lleno de _jargon _y donde cometer un error sale caro, pero por contra, el potencial beneficio es muy interesante. ¿Y por qué si no tengo ni idea de en lo que me estoy metiendo, sigo adelante? Primero: quiero ahorrar y que mis ahorros crezcan lo máximo posible, como le gustaría a cualquier hijo de vecino. Segundo: aunque en este pu..

I just got home after enjoying a couple of days in the PAPIs.io Connect conferences in Valencia. And they’ve been great! There have been sessions about Machine Learning, Deep Learning, APIs, AI, BigData and many more. Oh, and there have been drones too. To summarize, the ecosystem surrounding BigData and AI technologies is amazing and currently is really on fire. In my humble opinion, I think this quote from Ramón López de Mántaras ’....

Packages in Java is a quite simple and straightforward concept of the language. It’s there from the beginning and it’s commonly used by every Java programmer. In a few words, these are the rules you have to follow to create a class inside a package (spoiler: which are not completely true, as we’ll see later): Package statement must be the first one specified in a java class file A package namespace must match the physical path of the file....

Day after Codemotion 2015, this is my overall opinion of the event: meh. Don’t get me wrong, technical sessions have been quite interesting, full of really nice people and organization must have worked really to get the event running. But, in my opinion, this event is dying of success. Way too many assistants, making really hard to walk from one session to another (even having 15 min between them), or having to arrive 30 min before start if....

In little less than a week, a new edition of Coursera’s course, Principles of Reactive Programming from Martin Odersky, Erik Meijer and Roland Kuhn, is launching. This course is a follow-up of Principles of Functional Programming in Scala , which I took in its first edition and which I enjoyed a lot. I’ve regretted missing out first edition of this second course for a long time (more than a year, in fact), so if you want to learn about..

Purpose of this post is to provide a glimpse of the new features included in Java 8 that shift this language towards a more Functional Programming paradigm. But before, let’s define what we understand for Functional Programming (FP). Functional programming key characteristics include: Higher Order Functions Pure Functions and Immutability Tail Call Recursion Higher Order Functions for a FP language means that functions are considered ....

As March 11th, Pivotal dropped its financial sponsorship for Groovy , and despite of not really endangering it, as Groovy is an already well established language with a great community backing it, it raised many concerns, as the required boost a platform like this deserves was missing until now. Furthermore, its creator and project leader until lately, Guillaume Laforge, also recently stepped back in order to focus in Restlet. Also the....

It’s been a little more than a year since Java 8 was released (2014/03/18) and you might think that it’s a little too late for a What’s new in post. In fact latest public update available is 8u40, so let’s review not only what was initially included in Java 8, but what else has changed during this first year, up to release 8u40. Lots of changes were included in the initial Java 8 release, being probably the most notable of them, in my....

Welcome to jvmGeek ! This new blog aims to talk and discuss about the JVM ecosystem, with news and articles discussing about Java – the language -, and also about other JVM languages such as Scala, Kotlin or Clojure. But it won’t deal only about programming languages, but also about tools and libraries. You’ll find news, tutorials, code examples and more general articles, among other. From time to time I will also try to gather ev..

Every single working day I spend between 2 and 2.5 hours in a train. And I feel pretty lucky about this, mostly because is one single train, no need to pay attention for switch overs or other kind of public transports, and that allows me to invest that time in whatever task I want: podcasts, videos, blogging or even programming. And that’s what I want this post to focus in, because there are plenty of posts that explain how to use a Chromeb....

Watching Movies and TV Shows from online streaming sources is a pain, as you depend on the availability of the your ISP network and current status of the stream provider. Furthermore, you don’t always have an internet connection available when you want to spend some time in front of the TV. So downloading it it’s a much better way to go in order to avoid this issues (giving that you have to anticipate a little bit to get downloads finished)....

Para los amigos webmasters que deciden alojar sus ideas en beta y desarrollos básicos en Heroku, éste presenta una gran alternativa: es fácil de usar, no se requiere inversión inicial, y además, acelera de sobremanera todo el trabajo de sysoperations, puesto que no hay que hacer más que un simple git push heroku master para tener la app funcionando en línea. ¿El único problema? Las apps free en Heroku se duermen si, durante una hora, no rec..

During last year, I had the chance to work as CTO of a startup, working mainly within MEAN stack. I was happy, the technology I was working with was in a great hype and its community grew bigger and bigger with lots of projects popping up everywhere. But life is continuously changing, and I started to work in a new company within Java/JEE technologies. I was back to my first days as a professional computer engineer. Java ecosystem is hug....

Un viaje por el camino de la memoria Hace un par de años atrás, cuando TinyPic estaba cerrando sus puertas, proveí de un pequeño script en PHP que permitiría a quienquiera poder bajar las imágenes de TinyPic que aún estaban disponibles, sólo que TinyPic no te dejaba accederlas visualmente, a menos que conocieras la URL directa. Entre truco y truco, encontré una solución que programé para que los usuarios del ahora difunto TinyPic pudieran..

Function composition is one the key features (among others) of functional programming. Programming languages that offer higher order functions as a feature can potentially use function composition. But, still, programmers need to be aware of some key concepts to successfully apply this pattern in our code. Function composition, as defined on Wikipedia, is an act or mechanism to combine simple functions to build more complicated....

Una de las cosas que son más comunes a la hora de diseñar interfaces en Android son las interfaces Holo. Actualmente, el elemento que es más común — en conjunto con los menús laterales y las ActionBar — son los elementos tipo tarjeta, bastante comunes en el Play Store. Hay varias alternativas de implementación. La que más se repite es hacer un nine patch, que requiere cierto esfuerzo, pero lamentablemente, el resultado no es pixel perfect, ..

The way you structure your code is a key factor when you define your source code organization. It will make your life easier or miserable, and once this structure is established it will become a really tedious task to redefine it. That’s why you know about the different patterns available and choose the one fits your project best. But, why should I care about modules? Well, is the way Javascript offers to organize and encapsulate your cod....

Javascript is an old well-known friend that is growing rapidly and gaining traction since Node.js, a command line Javascript interpreter based on Chrome V8 Javascript Virtual Machine, was published. Its community is building great stuff , and more and more companies are moving into this stack, with a high success ratio. http://nodegeek.net Luckily for me, for my last two professional years I have been involved in one way or a....

Hoy me topé con algo de mi día a día: en un viejo disco duro de respaldo tenía unas copias de DVDs en formato bin/cue. Lamentablemente, Mavericks no me dejó montar los archivos bin ya que, técnicamente, Apple no da soporte a los archivos bin/cue de manera nativa en Mac, pero la solución es bastante simple. Existe un programa de consola llamado binchunker que convierte archivos bin/cue a ISO sin mayores inconvenientes. Eso sí, necesitas tene..

Como empresa de logística con unos 96.000 camiones y varios cientos de aviones, una buena..

Mi segunda idea de app móvil, en pos de probar performance En mis ratos, una de las cosas que hago es crear algunas piezas de código interesantes.

Una app que decidí lanzar a todo público: HD Wallpapers. Bá..

Code modularization, achieved in one way or another, is a technique a good developer must aim for because it helps keeping things small, well-tested and organized. And of course, it follows the DRY directive. So as a Node.js developer (and maybe contributor to the Open Source), creating and publishing an NPM module is one of those steps you will eventually face. Probably if any Node.js developer would have to pick an indispensable tool ....

The Node.js ecosystem is quite young and prolific: new tools appear almost every day or week, changing and turning upside down your current workflow, always trying to squeeze a little more productivity to your time and effort or simply making your work easier.

Talking about Node.js history, it’s talking a little bit about V8 history. But let’s start with a one line definition of what it is: Node.js is a platform built around Google Chrome V8 Javascript engine, to create lightweight, fast, scalable, event-driven and non-blocking I/O applications. So lets begin talking about Node.js origins, the V8 javascript engine. V8 is an opensource project by Google and it is in the very core of Google Chro....

Javascript Allongé @raganwald is one of the more refreshing coding books I have read in a big while. Usually when I face a programming language book, I skip the beginner chapters (if I already know the language, of course) and go directly for the juicy ones, but with this one I tried to follow it from end to end because I read some comments on twitter telling that the way basics are explained, become a really solid base for the language,....

In the previous post I gave a glimpse of the Javascript Promises Pattern (JPP). Now we are going to take a more in deep look into it and implement our (simplified) version of this pattern. First of all, let’s sow the code I we defined works: we had three operations (to make the example simpler, they all share the same code, but this is not a requisite), each of them expecting a set of arguments which are processed by an asynchronous ope....

I am sure you have heard about the javascript Promises Pattern, but if you haven’t, here is a quick and simple definition: a promise or future is an object that represents a future result, not yet obtained or calculated ( here you have a more complete definition). In fact, what is really nice about it is that allows you to define callbacks for async code in and more elegant and readable way. But wait a moment, what’s the problem with the....
